In 14 male dogs, the functional urethra was replaced by a bladder flap tube in a 2-stage procedure. In the 1st stage of the operation a bipedicle strip from the anterior bladder wall was tubularized around a 10F or 12F catheter. After 10 to 12 weeks the 2nd stage of the procedure was performed: the bladder neck was transected and sutured, and the cranial pedicle of the bipedicle tube was transected and pulled through the bluntly dissected pelvic floor muscles. From the distal end of the tube a perineal urostoma was created to facilitate radiological and urodynamic followup. Eight dogs completed a followup 5 months after the 2nd procedure. Urodynamic and x-ray studies were done preoperatively, after the 1st, and twice after the 2nd operation. All dogs were continent as a result of a mean functional urethral length of 8 cm. with a maximum closure pressure of 82.9 cm. H2O. Closure pressure was related to the tone of the smooth muscular tube and additional compression of the tube by the pelvic floor muscles. The method is considered to be applicable in cases of congenital defects or total loss of the functional urethra.
在14只雄性犬中，采用两阶段手术，用膀胱瓣管替代功能性尿道。在手术的第一阶段，取自膀胱前壁的双蒂条带围绕10F或12F导管形成管状。10至12周后进行手术的第二阶段：横断并缝合膀胱颈，横断双蒂管的头侧蒂并将其经钝性分离的盆底肌牵拉穿出。从管的远端做会阴尿口造口以利于放射学和尿动力学随访。8只犬在第二次手术后5个月完成随访。在术前、第一次手术后以及第二次手术后进行了两次尿动力学和X线检查。所有犬均能控制排尿，平均功能性尿道长度为8cm，最大闭合压为82.9cmH2O。闭合压与平滑肌管的张力以及盆底肌对管的额外压迫有关。该方法被认为适用于先天性缺陷或功能性尿道完全缺失的病例。
